Extract an ICO as PNG in your browser

Decode any Windows .ico — typically a favicon — and download it as a standard PNG. Multi-resolution ICOs render whichever size the browser chooses.

Quick Start

How it works

Pick an image, tune the options, then download the result. Everything runs in your browser.

  1. 01

    Pick an ICO

    Choose a .ico file. Browser-renderable ICOs are supported.

    Files stay in memory as an HTMLImageElement — the original bytes are never uploaded, and EXIF metadata is preserved until you explicitly transform it.

    Browser picks a size

    Multi-resolution ICOs contain several sizes — the browser chooses one (usually the largest).

    Encoder quality is exposed where the format supports it — JPEG and WebP get a 0–1 quality slider; PNG is lossless. Options re-render the canvas immediately.

    Encode PNG

    Re-encode the decoded bitmap as a lossless PNG.

    Pixel work runs on the Canvas 2D context — drawImage resamples with the browser’s bilinear filter and getImageData/putImageData back per-pixel passes.

    Download PNG

    Save the .png. Pair with the PNG to ICO tool for round-tripping.

    Downloads ship via a hidden anchor with an object URL — no server round-trip, and the file on disk is untouched. The output filename inherits a sensible suffix.

Pro tips

Browser-only image work that scales

Convert with quality control

JPEG/WebP let you pick a 0–1 quality. Default 0.92 is a good compromise of size and visible quality.

PNG isn’t free

Use PNG only for transparency or sharp edges. For photos, WebP is smaller at the same perceived quality.

Strip EXIF for privacy

Photo EXIF often contains GPS, camera model, and timestamps. Strip before sharing public uploads.

Watch the colour profile

Convert to sRGB before web export. Wide-gamut images render oversaturated in non-managed browsers.

AVIF when it’s available

AVIF beats WebP on size at the same quality. Detect support via <picture> with fallbacks.

Lazy-load below the fold

Add loading="lazy" on <img>. The browser handles scheduling — no IntersectionObserver needed.

Use Cases

When to use this tool

Common workflows it speeds up.

Repurpose a favicon

Pull the favicon PNG out of a downloaded site. Decoded into a Canvas 2D context — original bytes never leave the tab, so you can process customer-uploaded photos, internal screenshots, or sensitive diagrams without privacy concerns.

px-perfect

Edit then re-pack

Decode, tweak, then rebuild with PNG-to-ICO. Encoders expose quality 0–1 where the format supports it (JPEG, WebP); PNG and AVIF stay perceptually lossless. Pick 0.85 for web, 0.95 for archival, 0.7 for thumbnails.

quality-tunable

Design asset extraction

Lift icons from legacy Windows apps. Pair with the EXIF Stripper before sharing user-uploaded photos publicly. Camera serial numbers, GPS coordinates, and timestamps often hide in image metadata and leak more than the picture itself.

format-aware

Build pipelines

Feed PNG into modern build steps. Output preserves colour profile (sRGB) so it renders consistently across browsers, monitors, and print pipelines. Wide-gamut workflows can opt into Display P3 for modern Apple devices.

EXIF-safe

Quick previews

Inspect favicons without a hex editor. Re-runs only on option changes, never on window resize, so the canvas stays responsive on large images. drawImage uses the browser's bilinear filter for fast resampling.

client-side

Cross-tool sharing

PNG is universally readable. Downloads as .png, .jpg, .webp, or .avif with the correct MIME so editors apply native handling on save. The filename inherits a sensible suffix derived from the input.

FAQ

Frequently asked questions

Whichever size your browser chooses to render — usually the largest available.
Some ICOs contain unusual sub-formats browsers can&apos;t decode. Try a desktop tool for full control.
No. The conversion runs locally in your browser — your file never leaves the device.
Yes — ICO alpha is preserved in the PNG output.
Not in this tool — the browser picks for you. Use a desktop ICO editor for per-entry control.
